Does (3, 10) make the inequality y > 2x + 2 true?

Answers

Answer:

Yes, it makes it true

Step-by-step explanation:

Plug in 3 and 10 as x and y into the inequality:

y > 2x + 2

10 > 2(3) + 2

10 > 6 + 2

10 > 8

Since 10 is bigger than 8, this inequality is true.

So, (3, 10) makes the inequality true.

If the measure of GH is 30° and the radius is 6 meters, what is the arc length of GH?

Answers

Answer:

The length of the arc GH is approximately 3.14 meters (or π)

Step-by-step explanation:

The length of an arc whose measure equals the measure of the central angle Ф and the radius of the circle r is:

L = (Ф ÷ 360°) × 2π r

Let us solve the question using the rule above

∵ The measure of arc GH is 30°

Ф = 30°

∵ The radius is 6 meters

r = 6 meters

→ Substitute them in the rule above

L = (30° ÷ 360°) × 2π × 6

∴ L = [tex]\frac{1}{12}[/tex] × 12π

L = π

→ Use π ≈ 3.14

L ≈ 3.14

The length of the arc GH is approximately 3.14 meters (or π)

One health club charges a $44 sign-up fee and $30 per month. Another health club charges a $99 sign-up fee and $25 per month. What number of months will the cost be the same? Write an equation or inequality then solve it. Provide work

Answers

Step-by-step explanation:

Let x be the number of months for the 2 health clubs to have the same cost.

We have $44 + $30x = $99 + $25x.

Therefore $5x = $55 and x = 11.

The number of months is 11.

Two angles form a linear pair. One angle measures (10x - 63). The other angle measures (8x)". What is the value of the larger

angle?

O 180

O 72

O 135

O 108

Answers

Answer:

108 degrees

Step-by-step explanation:

Given

Let the angles be A and B

[tex]A = 10x - 63[/tex]

[tex]B = 8x[/tex]

Required

Find the larger angle

If both angles form linear pair, then the following relationship exist:

[tex]A + B = 180[/tex]

Substitute values for A and B

[tex]10x - 63 + 8x = 180[/tex]

Collect Like Terms

[tex]10x + 8x = 180 + 63[/tex]

[tex]18x = 243[/tex]

Solve for x

[tex]x = \frac{243}{18}[/tex]

[tex]x = 13.5[/tex]

Substitute 13.5 for x in

[tex]A = 10x - 63[/tex]

[tex]B = 8x[/tex]

[tex]A= 10 * 13.5 - 63[/tex]

[tex]A= 135 - 63[/tex]

[tex]A= 72[/tex]

[tex]B = 8 * 13.5[/tex]

[tex]B = 108[/tex]

Hence, the larger angle measures 108

there?
Number of high-quality version downloads:

Answers

Answer:

Number of high quality version downloads = 880

Step-by-step explanation:

Let,

x be the number of standard version songs downloaded

y be the number of high quality version songs downloaded

According to given statement,

x+y=1600        Eqn 1

2.8x+4.1y=5624     Eqn 2

Multiplying Eqn 1 by 2.8 to eliminate x

2.8(x+y=1600)

2.8x+2.8y=4480     Eqn 3

Subtracting Eqn 3 from Eqn 2

(2.8x+4.1y)-(2.8x+2.8y)=5624-4480

2.8x+4.1y-2.8x-2.8y=1144

1.3y=1144

Dividing both sides by 1.3

[tex]\frac{1.3y}{1.3}=\frac{1144}{1.3}\\y=880[/tex]

Hence,

Number of high quality version downloads = 880
